Only the central foundation pile of three available for the game.If in one of the reserve piles there is a card of the same value with the one which in the middle of the foundation one, it is at once put on the middle card.After that (in case there are no more variants) the next 3 cards are drawn from the deck, one at a time and the procedure goes all over again.
